Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Real-Time Monitoring for Ohio Basin Water Management
The Ohio River Division (ORD) of the Corps of Engineers operates 77 reservoirs in this basin for the purposes of flood control, conservation, hydropower, low flow augmentation, water supply,...
Modeling Boundary Layer Flow in Stormwater Detention Basins
An iterative procedure involving an implicit finite difference numerical scheme was implemented on an IBM personal computer for solving steady, uniform and nonuniform boundary layer flow...
Dual Drainage System Balancing Design Using Microcomputer Simulation
This paper describes the development and application of microcomputer software titled INTERHYD for design of a dual urban drainage system in Portland, Maine. The design problem consisted...
Ground-Water Drainage to Surface Mines Refined
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique...
Modeling Unsteady Flows in Large Basins: The Santa Cruz Experience
A case study modeling unsteady flows in a 3,500-square mile basin in the semiarid Southwest has been performed. The evaluation uses novel techniques of mathematical modeling in a data-intensive...
A Hydrologic Model Developed for Microcomputers
An event oriented hydrologic catchment model has been programmed for use on a microcomputer. Because the program is written in PASCAL, it uses features of this language that eliminate...
Microcomputer Applications in Flood Management
Historically Salt Lake City has been subject to flooding from spring snow melt runoffs. Even though the volume and the rate of runoffs were similar during both years, the 1984 runoff created...
Data Acquisition and Analysis of Pressure Fluctuations in Hydraulic Jumps
The paper reports on a study to procure basic data on large pressure fluctuations in hydraulic jump stilling basins. Interest in pressure fluctuations relates to: the effect of dynamic...
SWRRB.80: A Basin Scale Model for Microcomputers
The SWRRB (Simulator for Water Resources on Rural Basins) model was developed by the USDA Agricultural Research Service to simulate the daily stream flow, and sediment loads from agricultural...
Computer Keeps New Orleans: Head Above Water
The city of New Orleans has been beset with drainage problems since its founding in 1718. A major drainage system was installed in the city in the late 1800s, but it has grown increasingly...
Drainage Tunnels Save Freeway Link
A 15 mile section through downtown Phoenix will complete Interstate 10. After years of delay, the project is now close to completion. The project required construction of 6.5 miles of...
Development and Management Aspects of Irrigation and Drainage Systems
The 1985 Irrigation and Drainage Division Specialty Conference held in San Antonio, Texas on July 17-19, 1985 covered major topics on watershed management and water conveyance, drainage...
Drain Maintenance in the Imperial Valley
Imperial Valley, located in the southeast corner of California is one of the most intensely irrigated areas in the world. Since Colorado River salinity is currently about 800 mg/l (1....
You Need More Than a Plumber's Helper
Maintenance of subsurface drains may be the least understood and most neglected of all maintenance activities carried out by irrigation districts. Few irrigation districts have a maintenance...
Physical Evaluation of a Buried Drainage System
The drainage problem in the 600,000 acre (1. 5 million ha) Westlands Water District (District), located in the Central San Joaquin Valley in California is that of a perched saline groundwater...
Microcomputers in Urban Drainage Design
Microcomputers offer an inexpensive method for increasing the efficiency and effectiveness of drainage design personnel. This paper discusses some of the benefits and uses of microcomputers...
Assessment of Drainage Infrastructure for Urban Areas
Public concern about the adequacy of the urban drainage system rises and falls with the rainfall patterns. Because the 'problem' depends on many variables, including...
Data Base in Your City's Future?
The city of Bellevue, Wash. computerized its public works maps in 1979 because Bellevue was using the county's maps, and their updating wasn't keeping up with suburban growth. Now this...
Groundwater Basin Storage in Southern California
The feasibility of implementing a groundwater storage program in the Chino Groundwater Basin (Chino Basin) to increase the firm yield of the SWP (California State Water Project) is considered....
